CVE-2025-61455: E-commerce 1.0 SQL Injection Vulnerability

CVE-2025-61455 Overview

CVE-2025-61455 is a critical SQL Injection vulnerability affecting Bhabishya-123 E-commerce version 1.0. The vulnerability exists within the signup.inc.php endpoint, where the application directly incorporates unsanitized user inputs into SQL queries. This flaw allows unauthenticated attackers to bypass authentication mechanisms and gain full access to the application and its underlying database.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to bypass authentication, extract sensitive data, modify database contents, and potentially achieve full system compromise.

Affected Products

• Bhabishya-123 E-commerce 1.0
• Applications utilizing the vulnerable signup.inc.php endpoint

Technical Details for CVE-2025-61455

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs due to improper neutralization of special elements used in SQL commands within the signup.inc.php endpoint. The vulnerable endpoint fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating a classic SQL Injection attack surface.

The vulnerability is exploitable over the network without requiring any authentication or user interaction. Successful exploitation grants attackers the ability to read, modify, or delete arbitrary data from the database, bypass authentication controls, and potentially execute administrative operations on the database server.

Root Cause

The root cause of CVE-2025-61455 is the direct concatenation of user-controlled input into SQL query strings without proper sanitization or the use of parameterized queries. The signup.inc.php script accepts user input and constructs SQL statements dynamically, allowing malicious SQL code to be injected and executed by the database engine.

Attack Vector

The attack vector for this vulnerability is network-based, targeting the signup.inc.php endpoint. An attacker can craft malicious HTTP requests containing SQL injection payloads in the input parameters processed by the signup functionality.

The attack flow involves sending specially crafted input to the registration endpoint that includes SQL syntax designed to manipulate the query logic. Since no authentication is required to access the signup functionality, any remote attacker with network access to the application can attempt exploitation.

Successful exploitation enables attackers to:

• Extract sensitive user credentials and personal information
• Bypass authentication to access privileged accounts
• Modify or delete database records
• Potentially escalate to remote code execution depending on database configuration

Detection Methods for CVE-2025-61455

Indicators of Compromise

• Unusual database query patterns originating from the signup.inc.php endpoint
• Web application logs containing SQL syntax characters in POST parameters (e.g., single quotes, UNION statements, OR conditions)
• Database error messages in application responses indicating malformed queries
• Unexpected authentication events or privilege escalations following signup attempts

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block common SQL injection patterns in requests to the signup endpoint
• Implement input validation monitoring to alert on suspicious characters or SQL keywords in user registration parameters
• Enable database query logging and configure alerts for anomalous query patterns or syntax errors
• Monitor HTTP request logs for payloads containing SQL injection indicators targeting /signup.inc.php

Monitoring Recommendations

• Configure real-time alerting for SQL syntax patterns in application input fields
• Establish baseline metrics for database query volume and alert on deviations during signup operations
• Implement integrity monitoring for database tables containing user credentials and sensitive data
• Review authentication logs for successful logins following suspicious registration attempts

How to Mitigate CVE-2025-61455

Immediate Actions Required

• Remove or disable the vulnerable signup.inc.php endpoint until a patch is applied
• Deploy WAF rules to block SQL injection attempts targeting the signup functionality
• Audit database access logs for evidence of prior exploitation
• Review user accounts created recently for signs of malicious activity or unauthorized access
• Implement network-level access controls to restrict access to the affected application

Patch Information

No official vendor patch information is currently available for CVE-2025-61455. Organizations using Bhabishya-123 E-commerce 1.0 should contact the vendor for remediation guidance or consider implementing the workarounds described below.

Additional technical details are available at the GitHub PoC Repository.

Workarounds

• Implement prepared statements and parameterized queries in the signup.inc.php script to prevent SQL injection
• Deploy a web application firewall with SQL injection protection rules enabled
• Apply strict input validation to reject SQL metacharacters and keywords in user-supplied fields
• Consider temporarily disabling the signup functionality until proper remediation can be implemented
• Implement database account least privilege principles to limit the impact of successful exploitation
